Prediction of weaning outcomes from mechanical ventilation in critically ill patients based on the combination of ultrasound parameters of the heart, lung, and diaphragm: a prospective observational cohort study
Prospective observational cohort study identifies ultrasound parameters predicting weaning outcomes in critically ill patients, suggesting enhanced outcomes assessment.
Key Points
A composite model integrating ultrasound parameters achieved an AUC of 0.951, indicating high predictive accuracy for weaning outcomes.
Significant differences in diaphragm excursion, diaphragm thickening fraction, and lung ultrasound scores were noted between weaning success and failure groups.
Ultrasound parameters such as left ventricular ejection fraction predicted weaning outcomes with AUC values above 0.7, demonstrating their clinical relevance.
The study involved 74 critically ill patients, and significant predictive performance was noted for individual ultrasound measures.
